2 memory strength (low, high) x 2 encoding variability (low, high) within-subjects, between-blocks recognition memory design.
- A: High Strength, high EV
- B: High Strength, low EV
- C: Low strength, high EV
- D: Low Strength, low EV
Individual-level plots of data, model fits and predictions of equal-variance Gaussian SDT (EVSDT, 6 parameters), unequal-variance Gaussian SDT (UVSDT, 7 parameters) and Gumbel SDT (Gumbel, 6 paraneters).
Split by condition, and winning-model (in tabs).
Plots:
- A: Comparison by Delta AIC, cut-off at 15
- B : Parameter estimates (con. = nlminb convergence output)
- C: zROC of data and model predictions (lines fitted by y = x^2). Note: scales vary by plot
- D: frequency of responses observed (bars) and predicted (symbols)
- E: residuals of predicted proportion of responses to observed data (+ means model predicts higher proportion of responses) in all response categories. Note: y-scale varies by plot
